Monitoring the FSS

You can use the prstat command described in the prstat(1M) man page to
monitor CPU usage by active projects.

You can use the extended accounting data for tasks to obtain per-project statistics
on the amount of CPU resources that are consumed over longer periods. See
Chapter 4, Extended Accounting (Overview) for more information.

How to Monitor System CPU Usage by Projects

To monitor the CPU usage of projects that run on the system, use
the prstat command with the -J option.
